Prolapse of the rectum, long-term results of surgical treatment

Abstract

This study evaluates patency and functional results of abdominal and perineal treatment approaches to prolapse of the rectum. A database search identified patients operated upon for prolapse of the rectum. The operations were abdominal or perineal approaches. The patient's records were reviewed, patients alive were contacted, and a self-report form evaluated functional results. Patients were followed until the prolapse recurred. A primary operation for prolapse of the rectum was performed in 56 patients. Median age was 59 years (range 20-87) and 78 (40-91) for abdominal and perineal approaches, respectively (p < 0.001). The average length of the prolapses was 8.7 cm (2-25) and 8.6 cm (2-15) for abdominal or perineal approaches. All prolapses treated with a Thiersch's operation recurred within a few months and all prolapses treated with the Delorme's operation recurred within 5 years, whereas the 5-year patency of the abdominal approach was 93% (p < 0.001). No prolapses recurred after mesh rectopexy and the 5-year patency of resection rectopexy was 86%. The abdominal approaches improved stool evacuation and constipation significantly, and anal leakage improved somewhat (p = 0.065). The median hospital stay was 11 (4-20) and 7 (2-155) days after abdominal and perineal approaches (p = 0.003). Complications occurred in 20% of patients. The patency of abdominal approach to prolapse of the rectum is better than that of perineal repairs. The abdominal approaches also have a favorable effect on constipation and anal insufficiency. Perineal approaches should be reserved for patients with a very short life expectancy.
